To all whom it may concern: Be it known that I, RoMEDI-Us PANZL, re-

siding at Merritton, county of Lincoln, Do-

ers and tanks used for storing or boiling of corrosive chemicals as heretofore produced f of hydraulic cement mixed with sand and bf tiles applied thereon being from five to seven inches thick greatly diminishes the capacity of the vessel and is not absolutely impervious to such corrosive fluids.- Superlining with glazed acid-proof tiles is not sufficient to protect the lining material from dis integration. Hydraulic cement and sand mixed with water do'not unite so absolutely as to fully eliminate every particle of air,

' and the water used in mixing the dry ingredients is not fully absorbed chemically. The air and superfluous water cause what is known inthe art as blowing, (swellingand contracting of the mass,) whereby cavities and devices are formed in the body of the lining through which the corroding chemicals penetrate and destroy the body of the vessel or conduit. I Having experimented extensively with the end in view to devise an acidproof material for such linings which should be free from such defects, I have found that egnnsitieaethxmanlicnrmntrem n11, chamotte, and quartz, or some-other silicious mterrarnniy powdered and then mixed together with diluted silicate of soda, will produce a material that does not draw or crack when applied to the walls of the vessels in plastic state and which is absolutely im-I permeable to and proof against any corrosive fluid used or known in the arts. The proportion of these materials may be moderately varied, according totheir qualities", from the following standard expressed; in parts measured by volume: twenty-six parts of ca e oi goda twenty-one parts of silicious twenty-four parts 0t pure iwr. 1n preparing this material the chamott-e and quartz are finely pulverized and thoroughly mixed with the cement 'while yet dry. The silicate of soda will give the desired result if the pro portion is made as stated above. The dry ingredients are moderately heated and mixed with, wet ingredients. is M done, their temperature must be.

'rsvessels containing the materials should be kept moderately heated,and the mixing should be done in a closed vessel, "The plastic mass'produced by mixing the pulverized materials with the diluted silicate ofsoda is applied while yet hot to the vessel .to be lined. While this is being done, the vessel must not, however, be warm, and if the lining, for instance, of a boiler is being done while other adjacent bToiTfi; are in operation the boiler must be cooled during the operation by spiayin g it with cold water from the outside, by covering it with wet rags, or in other suitable manner. The surface to which the lining is to be applied must be thoroughly cleaned and the first layer, as I term it, rubbed in. This is necessary to lining and the wall of the vessel. material sticksgea my.

When the liningis com- 5 pleted, the vessel can be put to its use immediately. If this, however, is not done, the vessel ought to be partly filled with water, which is to be kept moderately heated until the ligipgisfnllyhardepggd. When finished, to the surface of the lining is perfectly smooth and will safely withstand any use to which the vessel may be put. No other covering, such as tiles, is necessary even for boilers wherein the boiling material is to be agitated by mechanical device. A lining composed of the described material and applied in the described manner is practically indestructible. It will withstand the action of any corrosive fluids, even the fumes of concentrated sulfuric or nitric acid, and will not crack.

If superlining with tiles is required, such tiles may be applied immediately upon the lining. No other binding material is necessary between the lining and the tiles, and

crevices between the adjoining tiles are filled and the tiles are cemented together with the same material as used for the lining. The tiles are applied in similar manner to round vessels.

If uartz is not obtainable, then ulverized "lass {twelve per cent.) and slate {nine per cen may be used, instead. e ining com- 3 posed of material containin ulverized "1 ss 5 and slate in place of quartz is equally proof against corrosive fluids, though less compact and hard, and consequent-lyless capable to resist abrasion. For lining of boilers or pulpdigesters, wherein the boiling mass is thrown with considerable force and velocity against 40 the walls, the material composed of cement,

chamotte, and quartz is better suitable than the substitute containing glass and slate.

The above-described composition of material is suitable also for another use. It is often necessary to divide a tank or other vessel for holding of corrosive fluids in two or more compartments. Such partition-walls were heretofore made of the same material as be required by erecting a grate of bars or stretching a strip of suitably-strong wire-netting where a partition is to be constructed and then applying the lining material to it. When sufficient thickness is obtained, the surfaces of the partition-wall are finished on both sides. Such partition-wall will be found sufiicientlystrongforall purposes. Thegrate or netting serves to sustain the wall and secure it against breaking. Such combination of my improved lining material with a grate or wire-netting may be used for constructing tanks independently of any other material in such manner that instead of lining a tank the tank may be constructed of the lining material applied upon a grate or netting of wire or othersuitable material. For such purpose a suitably-shaped grate of iron bars about one-fourth to one-half of an inch thick, fastened together by ties of wire, is used; This grate is set up in wooden planking of somewhat-larger dimensions, and the material is applied to it. The wooden planking is removed after the plastic material hardens. Any tank thus constructed is absolutely safe, and even boilers exposed to comparativelyhigh pressure may be thus built with safety if the wooden planking is retained and bound together by iron bands.

I claim as my invention and desire to secure by Letters Patent- 1. A composition of matter for acid-proof lining of boilers, tanks and similar vessels, composed of hydraulic cement, chamotte, some silicious material, water andsilicate of soda.

2. A composition of matter for acid-proof lining of boilers, tanks, and similar vesse'ls,-=

composed of hydraulic cement, pulverized chamotte and soda. I

3. A composition of matter for acid-proof lining ofboilers, tanks, and-similar vessels, composed of twenty-six per cent. of hydraulic quartzand of diluted silicate of cement, twelve per cent. chamotte, twentyone per centjof quartz and of a suitable quantity of diluted silicate of soda.
